The E-4C Survivable Airborne Operations Center (SAOC) is a United States Air Force program to develop a replacement for the E-4B National Airborne Operations Center (NAOC), a strategic command-and-control military aircraft used as a mobile command post for the National Command Authority in emergency situations. The current E-4 platforms were built in the 1970s. The airframes are reaching the end of their operational lifespans and support costs are increasing. Because of this, in 2019, the USAF began a program to develop a new platform. This program will take several years to complete. The E-4s will continue to fulfill the role in the meantime. In 2024, Sierra Nevada Corporation (SNC) was selected to develop the aircraft. The aircraft will be based on the 747-8I, with SNC collaborating with General Electric.
